So me and the wife got in a argument about the best way to keep our dogs from yelping when in their crate.  I have always been told that the best way is to keep making a loud noise when they start and tell them no that they would stop.  She on the other hand thinks that ignoring them will work.  Well they have been yelping for the past hour and will not stop.  I need help what is the best way to train them?
